The Darlington Upgrade Project is another important stage in the delivery of Adelaide's North-South Corridor and will deliver an upgrade of approximately 3.3 kilometres of the existing Main South Road, including:

  • A non-stop motorway between the Southern Expressway and north of Tonsley Boulevard
  • A  non-stop motorway passing underneath Flinders Drive, Sturt Road, Sutton Road/Mimosa Terrace, Ayliffes Road bridge and Tonsley Boulevard
  • Grade separation of the Main South Road/Ayliffes Road/Shepherds Hill Road intersection
  • Main South Road (at grade) surface roads along both sides of the lowered motorway to provide connections to Flinders Drive, Sturt Road, Tonsley Boulevard and most local roads
  • Full free flow interchange at the Southern Expressway/Main South Road with dedicated ramps providing direct access to, and from, the new motorway and Main South Road
  • A two-lane overpass for northbound traffic travelling east on to Ayliffes Road

The $754.5 million project was jointly funded by Australian and State governments ($603.6 million federally funded and $150.9 million state funded). The project was open to traffic in 2020
